1' 125 concern y El that 1, "loss BBRGSTSGBL oi the finitecl gtstes resicliug zit .llhi!lelemiei in the count of {inside and Stet-e01 "Wisconsin; have invented certain new 'sncl useful Improvements in lileat- Tenderers; and I do herehy declare the following to be a full, clear, and. ah-113i; description of the invention, such as will enable others skilletl iii-tile art to which it apperteiizs tomelse and use the same. l

I My invention refers to meat teuclerers. 4' The, object ofmy inventioniis to provide smeans for rendering meat, especially heel steak,-1tenflei? 21ml. palatable, and yet leaving the steak in practically its normal shape, and.

is, not to be, confounded with e meat grindein Iii the rlrcwingsherewith which are made sportof this application Figure l is front elevation of the tenderer atta.cheri to the *2 is eml view showing the cog-geor1ng, and Fig. 3 is a vertical sectional view on the line :1a

rfller which is con lei; structiu'e anrl is conposecl of pl out; of mountcrl central-shalt A plural h'zwing sharp cutting edge \3 and a pin relity of notches i" cut at regulur in elvals in said ec e mount .i-

smooth 'l 1 ting pm construct 2.1g on placed upon are alterlisgir 8, the cutting blades on the disks 8 hepositioned hallway between the notches nlhe clislas 5 in slinement, the notches valso es the disks to form roller l. This combination of disks is then helrlfirmly in place by two nuts being run on the shaft which is threadecl near each end to receive the nuts, the c lislrs may be easily .anclv quickly remoyefi 3 to sharpening or repairs by removing one of the nuts after the shaft has been removed Irom the frame. The above clescrihecl arrangement of the disks and out n kept in olinement when assembling ting blades form a l'ollepzw nit will make 70 two rollers.

The two side pieces of the frame are of metal ounrceted at their upper portions 15,

between the for s of which are slfiably pos= sitionecl the hoxin 16 carrying the bearings of the g'ournals anal l lower encls of said side ll therewith are locoteol 1'? provided 'With screw threadeol 9 Tllig Winged heads, sei bolts J11 threaded opening in saicl thus supplying a means for fastem g sting between two parts of the bifurc (l ends 15 of the two side ieces aml ont'p of the ooxings are the ends of a tension spring 19. The tension of said'spring 19 is regulated by threaded bolt having a 1 winged head or a thumb screw) 20 passing through a threaded orifice in the center of the top cross-piece 9 which is of cast metal formed thicker in its center portion antlhaving a rib cast along its top surface at '1 right angles to the plane thereof for the purpose of adding strength to the casting. By means of said spring the operative space between the rollers is controlled. The ex treme ends of the bifurcated portions of the 1 lsairl members terminate in threaded portions which passthrough openings in the 7 reduced forming a shoulder thereon and the" reducedportion "is threaded and provided with a nut. The shoulder rests against the inside portion of-the side pieces, the vreduced portion extending therethrough and the nuts being run on the threaded portion, hold the sides in fixed arallel relation to each other, and add ri i ity to the frame.

On either side of t e frame at a point slightly below the top of the lower roller 3 two metal shelves 22 and 23 extending at right angles to the frame and parallel with the surface of the rollers, are placed to receive and support the steak While being run between the rollers. A third metal shelf 24 is also attached to the frame on the front side thereof and above the before mentioned shelf 23 for the convenience of the operator.

1 The entire structure being composed of metal can readily be cleaned and kept in a sanitary condition. 1 v

In operationthe tenderer having been fastened to a table b the clamps, the steak is placed upon one o the shelves and the crank is turned to rotate therollers, the steak is then placed so that it will pass between the rollers, the sharp edges of the cutting members on the top roller cutting short gashes in scription is deemed unnecessar upon a shaft,

the steak but not entirely severing the portions. The steak may be run through backward and forward as frequently as may be necessary to reduce the steak to the required condition, thus quickly and much more effectively accomplishing the result aimed at by pounding the steak as is common practice.

From the foregoing description it is believed that the construction, advantages and manner of using my invention have been made clearly apparent, and that further dev What I wish to secure by Letters Patent is:

In a meat tenderer, a cutting roller comprising a plurality of disks having sharp cutting edges, the said edges having a plurality of notches at regular intervals therein, a plurality of smooth disks of less diaineter and" greater thickness and having cutting blades across the face thereof, and of less len th than the width of the said disks, the sai disks being alternately assembled i whereby longitudinal and transverse disconnected cuts are made.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
